, This invention relates to lubricators of'the type disclosed in applicants copending'application for patent, Serial No. 500,523, filed December 6, 1930, and is intended for continuously or intermittently delivering measured quantities of lubricant to a plurality of conduits, each leading to. a hearing or journal.

The purpose ofthe invention is to provide improved means for regulating the oil feed so that each hearing may receive oil only at the correct rate for such bearing, and without waste. A .further purpose of the invention is to provide an improved lubricating feed device having adjustable measuring eleenable an extremely fine feed to some of theoil conduits, such as a few drops per hour, and

a much greater but definite feed to other conduits.

The objects of theinventi'on are accom plishedby a construction as shown inlthe -clrawings,"' wherein Figure 1 shows the improved lubricator in front elevation. j a p Fig. 2'is a plan view of the lubricator with the cover and motor removed and partly in dicated in section by the line 22 of Fig. 1;

' vertically arranged oil receivingconduits, the' lower ends of which conduits are coupled to conduits leading to' various journals of the machine which is to be lubricated. The vertically disposed conduits within-the container and partly in sec- 7 tion to illustrate the oil-receiving-conduit 1931. Serial no. 520,313,

are each com-posed of pair oftelescoping sleeves, one of which is vertically adjustable above the oil level in the container and has an inlet for receiving oil. 'Slidably mounted upon these conduits are oil lifting devices all of which are intermittently reclpriocateda uniform distance along the conduits inorder to pick up a definite quantity of the lubricant and'raise it so that more or less of the lubri- 1 I The conduits which receive thelifted lubricant are adjustable vertically.independently of each other, thus varying the inlet port levels thereof, and in this manner regulating the inwardfiow of the lubricant therein. The portsmaybe of various forms and receive only a drop,or a greater quantity, of the lubricant each time the delivery elements are lifted. f

These elements are further controllable by a continuous operation thereof, or intermittently at any desired rate.

Referring to' the drawings, the oil container 1 is preferably. a hollow casting from light metal and is provided with apertured ears 2, by means of which the lubricator is "supported. The upper end ofthe casting 1 is open and supports the casting 3, forming a continuation thereof in carrying oil-conduit-adjusting elements 4. The upper end of the lubricator is closed by a cover plate 6.

.vided with a hinged closure .8 and an oil level indicating glass 9- which' may be viewed throughthe opening 10. 1

A row'of aperture'd bosses 11 are formed on the bottom of the container 1 and support oil conduits which extend upwardly therefrom toabove the normal level of the oil in container 1. These conduits are formed of telescoping elements 12.and 13, the outer one 13 is adjustable vertically along the elements 12 to bring oil receiving inlets l4, formed therein, at diiferent heights above. the oil level. Above the inlets '14, vthe'elements v13 carry fast thereto grooved collars 15. Each reguiated with reference to. the upper end of of these collars is engaged by a pin 16 eccentrically carried'by one of the conduit ad justing elements 1.

The heads of these elements are slotted at 17 to-receive a screw-driver by means of which, they may be turned for the purpose of raising or lowering one of the conduit elements 13 ,along the conduit 12 upon which it members 4.

is slidably mounted. By this means, the vertical position of the openings 14 may be the stroke of oil lifting members 18 which are slidable along the conduit elements 13;

The adjusting members 4 are held to their angularly adjusted positions by" a spring pressed plunger 19, Figure 7, engaging the inner toothed surface 20 of the heads 21 of The adjusting members 4 are held against longitudinal displacement by a bar 22, Figure 8, fitting a groove 23 in the casting 3 and passing through grooves 24 of theadjusting elements 1. Grooves 24 prefverablyextend only part way around the adjusting elements, as indicated in FigureS jtolimit the; angular adjustment of the latter. The oil lifting members 18, which are reciprocated along the tubes 13, have oil receiving pockets 25 at their upper ends and are provided with annular grooves 26 for I head 27 along shaft 30, the latter has a con-V tlnuous right and left pitched intersecting groove or guideway cut therein and enure 3, retained in the cross head by nut 35, Rotation of shaft results in a'uniform receiving a cross head 27. The slot 28 of the" cross head, into whlch the lifting elementsare fitted, is enlarged at 29 for receiving the lifting elements when. assembled in the.

cross head;

.. The cross head 27 is reciprocated by shaft 3O resting upon hearing 31, Figure 3, and connected at its upper end by a coupling 31 to a short vertical shaft,.not shown, butv carried in the motor casing 32 and geared to the motor shaft;

F or the purpose of reciprocating the cross gag-ed by a toothed pin or follower 34, Figreciprocation of the cross head 27 and the oil carriers 18 along the conduit elements 13, the amount of oil received by each of these elements depending upon the vertical adjustment thereof.

. The. location of openings 14% in the conduit. elements 13, with reference to the UPPQI",

most position of the oil carriers 18,.regulates the quantity of oil which flows from the.

' pockets 25 into the conduits.

- The bosses 11 at the bottom'of oil container 1 are exterlorly threaded to have coupled therewith sight feed gauges 36, to which are; I attached the eondu1ts 37 leading to the bear-.

ings or journals of a machine to, which the lubricant 1s supplied.

V In theoperation of the lubricator, the cross head 27 is either intermittently 0r continuously reciprocated with uniform strokes along the conduit elements 13 by any suitable drive means, such as the motor connections illustrated in the drawings. The oil carrying devices 18 are thus regularly dipped into the lubricant and carried upwardly above the normal level of the oil in contalner l. The amount of oil which flows from the pockets 25 of the lifting elements through apertures 14 in tubes 13 depends upon the vertlcal p0- The tubes are verparticular machine, the lubricator requires no furtherattention, except that of proper oil supply. The device requires no valves or wicks, either of which may become more or less clogged and fail to deliver at the correct rate, particularly when an extremely low rate of feed of the lubricant is required.
